CVE-2026-87916: CWE-200 Information Exposure in WPBot
The WPBot WordPress plugin before 8.6.0 does not perform any capability or nonce check on the AJAX action that lists stored chat sessions, allowing unauthenticated attackers to retrieve the name, email address and phone number of every chat visitor by requesting a wide date range.
AI Analysis
Technical Summary
CVE-2026-87916 is an information exposure vulnerability in the WPBot WordPress plugin. Versions from 8.4.9 up to but not including 8.6.0 do not validate user capabilities or nonce tokens on an AJAX endpoint that lists stored chat sessions. This lack of access control enables unauthenticated attackers to request chat session data over a wide date range and obtain sensitive visitor information including names, email addresses, and phone numbers.
Potential Impact
The vulnerability allows unauthorized disclosure of personally identifiable information (PII) of chat visitors. Attackers can access names, email addresses, and phone numbers without authentication, potentially leading to privacy violations and targeted phishing or social engineering attacks.
Mitigation Recommendations
Upgrade WPBot to version 8.6.0 or later, where this vulnerability has been fixed by adding proper capability and nonce checks on the AJAX action. No other mitigation is indicated by the vendor advisory.
